Definitions
- the invention is a method and a device for energy recovery during manufacture of asphalt in bulk.
- Bag filters on the other hand, have a considerable limitation in that the cloth is destroyed at temperatures exceeding about 230° C. Furthermore the compositions of bitumen will condense and pack the clock in the bag filters.
- FIG. 1 discloses schematically a total plant for manufacturing asphalt in bulk
- FIG. 2 discloses a vertical section through the device according to the invention.
- FIG. 1 discloses a total plant for manufacturing asphalt in bulk according to the invention. Two bulk fractions are supplied through feeding pockets 24, whereas filler is supplied from a silo 25 to a conveyor 28 which transports the bulk to the device according to the invention.
- the drawing discloses also bitumen tanks 22, an oil tank 23, doser device 27 for recirculation and a conveyor 26 for withdrawal of the end product.
- the waste gases from the mixing drum 29 are directed by channels 30 to the device 21. After treatment in the device, the bulk is transported by a transport means 31 to the input of the mixing drum 29.
- the device 21 is disclosed in vertical section on FIG. 2.
- the conveyor 28 transports the bulk to the elongated funnel 6 where the bulk is distributed equally along the length of the funnel by a scraper conveyor 8.
- a packing of bulk generally denoted 11, is created. This packing or plug prevents air in the environment from penetrating into the device 21.
- a cam 12 divides the bulk in the funnel into branches for treatment in symmetrically arranged sets of inclined planes.
- Each inclined plane comprises a lower inclined wall 1 and an upper inclined wall plan 5 being arranged in parallel and at a distance from each other.
- the free distance between the walls is 200 mm and the sloping angle is 14° to the vertical.
- Each inclined wall 1, 5 comprises a grating 3, 13 to which horizontally fixed ribs 2, 4 are arranged.
- the ribs 2 in the first wall 1 are arranged sloping downwards against the second wall 5, the ribs thereby partly overlapping each other.
- the ribs 4 in the wall inclined plane 5 are arranged vertically.
- the combustion gasses supplied to the device from the mixing drum 29 by channels 30, are supplied to the lower side of the first inclined wall 1 and pressed through the ribs 2 against the bulk masses sliding down the inclined plane from the funnel 6.
- the gasses disperse a substantial part of their heat energy to the bulk masses and simultaneously are cleaned of pollutants.
- the gasses are then sucked up through the ribs 4 in the second inclined wall 5 and further directed to the environment.
- vibrator devices 14 are used to vibrate the inclined planes. Further, to prevent the bulk masses from packing or compressing, the lower edge of the ribs 2 are provided with teeth comprising alternating recesses and webs, the webs in a rib being arranged above the recesses in the rib beneath. The bulk masses are thereby disengaged as they fall from rib to rib.
- a conveyor is arranged at the bottom of the inclined planes for transportation of the bulk masses which have been treated.
- the conveyor is permanently set to maintain a packing or plug 7 with bulk masses, preventing air from penetrating into the system from the environment.
